EEG investigation of the oscillatory fingerprints of the Rubber Hand Illusion
We use the so-called rubber hand illusion to investigate the brain mechanisms underlying the internal body representation. The rubber hand illusion (RHI) is a widely used paradigm where participants watch an artificial rubber hand (visual cue) being stroked in synchrony with stroking on their own occluded hand (tactile cue). This visuo-tactile manipulation alters bodily experience. It induces the illusion that the rubber hand (RH) is one's own hand and results in an illusionary postural recalibration of the internal body representation whereby participants mislocalize their own hand towards the rubber hand. The goals of this project are to identify the brain networks underlying the internal body representation and to examine how mechanisms of multisensory brain function lead to dynamic changes in bodily consciousness. Using EEG in combination with a visual-tactile stimulation device we will test for long-range coupling between temporal and frontal brain regions during the RHI, phase reset of oscillatory neural activity in somatosensory cortices by the concurrent visual input and mechanisms of stimulus-driven prediction.
